swift - 如何编写一个开关以在Swift中读取YouTubePlayerState？

我希望我的YouTubePlayer状态更改我的 View Controller 中的公共(public)变量。我在使用YTPlayer委托(delegate)功能和开关时遇到了麻烦。这是我的var ...

var ytps = String!

这是youtube状态功能...

func playerView(player: YTPlayerView!, didChangeToState state: YTPlayerState)
    {
        switch (state)
        {
        case YTPlayerState.Ended:
            // handle ended state
            print("Ended")

            break;

        case YTPlayerState.Paused:
            // handle paused state
            print("Paused")

            break;
        default:
            break;
        }
    }

如何获取YTPlayerState.Ended或YTPlayerState.Paused的状态，以将空字符串的值更改为“Ended / Paused”？

最佳答案

我想您可以将print("Paused")和print("Ended")替换为ytps = "Paused"和ytps = "Ended"。完整示例:

var ytps = String()

func playerView(player: YTPlayerView!, didChangeToState state: YTPlayerState) {
    switch state {
        case YTPlayerState.Ended:
            ytps = "Ended"
            break
        case YTPlayerState.Paused:
            ytps = "Paused"
            break
        default:
            break
    }
}
